United States Patent 3 274 637 PAINT APPLICATOR AN D ROLLER THEREFOR Ernest G. Schulze, 78 Black Oak Ridge Road, Wayne, NJ. Filed Mar. 11, 1966, Ser. No. 536,563 18 Claims. (Cl. 522) This application is a continuation-in-part of my allowed copending application Serial No. 371,054, filed on May 28, 1964, now forfeited, which application is, in turn a continuation-in-part of my abandoned application Serial No. 325,422 filed on November 21, 1963 and which was previously copending with said application Serial No. 371,054.

The present invention relates to paint applicator rollers and more particularly to a painting roller suitable for use in applying paint to walls, ceilings and similar surfaces of buildings or the like and most surfaces regardless of texture such as cinder blocks, asbestos shingles and other rough and uneven surfaces.

More particularly, the invention relates to paint applicators of this type employing a spongy roller which cooperates, whenever desired, with a hinged flap member for applying paint to only one of two surfaces which meet at a corner and for applying paint in a slot such as that defined under an overhanging shingle, for example.

Conventional rollers of this type have the disadvantage that it is not possible to paint a ceiling, for example, up to its extreme edges. If the edge of the ceiling surface is approached too closely, undesired paint is applied to the wall. Unless the wall and ceiling are of the same color or the Wall is still unpainted, this paint must be removed. In any event, there will be an unpainted margin around the entire periphery of the ceiling surface which must be painted 'by hand using a brush or a separate specially designed roller.

The present invention avoids these disadvantages by providing a flap member which will bear against the wall surface to prevent the application of ceiling paint to the wall adjacent to the corner defined by the junction between the wall and the ceiling. The roller is spongy and resilient which permits it to be forced completely into the corner while the flap member operates as a guard or shield simultaneously deforming the roller into a flat-sided cylindrical configuration and confining the paint to the ceiling surface. In this manner, the entire ceiling, including its extreme edges, may be painted using the roller without the need for subsequently completing the painting at the edges by other means.

A feature of the invention resides in an effectively uniformly resilient spongy roller which is divided into separate inner and outer portions by a flexible impermeable barrier layer. The barrier layer prevents the penetration of paint into the inner core portion of the roller from which it would be difiicult to remove when cleaning the roller if the barrier layer were omitted. Unless removed by cleaning, the paint in the inner portion of the roller becomes hardened and impairs the resiliency of the roller.

In one embodiment, as originally disclosed in my application of November 21, 1963, the barrier layer extends over the ends of the inner core portion of the roller, the ends of the core portion being flush with the ends of the outer portion. In practice, however, any paint or moisture which leaks into the inner core portion becomes trapped by the closed ends and fails to evaporate. As a result, it has been found preferable to make the core portion shorter than the outer portion so that ends of the core portion are recessed within the projecting ends of the outer portion and are protected from contact with the paint by pressure distributing end washers.

The roller mounting is used with either of two interchangeable hinged flap members. One flap member is wider than the other and the wider fla-p member is used for painting only one of two surfaces which meet at a corner. The narrower flap member has a beaded edge and is used for painting the walls of a slot such as that defined by an overhanging shingle. In either case, the flap member comprises a pressure-applying portion which engages the spongy roller for deforming its normal cylindrical configuration and aiding in compressing it into a corner or slot, as the case may be.

In a further modification, the roller is revolubly mounted in a trough member formed of effectively rigid but somewhat resilient material. The fiap member is provided with a cam member which cooperates with an edge portion of the trough to retain the flap member in either of two positions. In one position the flap member is inactive and is maintained clear of the roller. The roller then operates as if the flap member had been removed. In the other position, the flap member is resiliently held slightly spaced from the roller so that the flap member is ready for use in applying paint to corners.

Various additional objects, features and advantages of the invention will become apparent from reading the following specification together with the accompanying drawing forming a part thereof.

Referring to FIGS. 1 and 2, the applicator comprises a cylindrical roller formed of spongy material such as a plastic foam. The roller 10 may be provided with a thin central tubular core 11, if desired. The roller 10 is freely revolubly mounted on a supporting shaft which comprises axially aligned portions 12 and 13. The shaft portion 12 comprises an extension 15 of reduced diameter which is freely slidably received in an axial bore 16 formed in the other shaft portion 13. A helical compression spring 17 in bore 16 yieldingly urges the extension 15 away from the closed end of the bore 16 so that the overall length of the supporting shaft 12, 13 may be shortened by compressing the spring 17. A stop pin 19 traverses the bore 16 and passes through an axially elongated slot 20 formed in the extension 15. The pin 19 retains the shaft portions 12 and 13 in assembled relationship while permitting the limited axial movement of the extension 15 in the bore 16.

The applicator comprises a housing designated generally as 21. The housing 21 comprises a cylindrically arcuate trough 22 to which end plates 24 and 25 are secured. A handle 27 is removably attached to the housing 21 by means of a threaded socket 28 fixed to the trough 22.

At its free end, the shaft portion 12 is provided with a flanged end member 29 which is threadedly secured thereto to permit replacement of the roller 10 on the supporting shaft 12, 13. A similar flanged end member 31 is attached to the free end of the shaft portion 13. Each of the end members 29 and 31 is provided with a stub shaft projection 32. The tWo stub shaft projections 32 are journaled in the end plates 24 and 25. By pressing on either end member to compress the spring 17, the shaft 12, 13 may be shortened sufliciently to disengage one of the projections 32 thereof from its associated end plate 24 or 25 thereby permitting the roller 10 and shaft 12, 13 to be removed as a unit from the housing 21.

A flap member 33 is mounted in the housing 21. A pivot shaft 35 extends along one edge of the flap member 33 being fixedly secured thereto. The flap member 33 is cut away adjacent to the ends of the pivot shaft 35 so that the opposite ends of shaft 35 may be freely journaled in the end plates 24 and 25. Adjacent to one end of the pivot shaft 35, the flap member 33 is cut away at 34 to an extent sufiicient to permit the mounting of a helical compression spring 36 on the adjacent end portion of the pivot shaft 35. By exerting axially directed pressure on the other end of pivot shaft 35, the spring 36 may be compressed sufiiciently to push the compression spring carrying end through the end plate in which it is journaled and withdraw the other end from its associated end plate. The flap member 33 may thus be readily removed from and replaced in the housing 21 for cleaning purposes.

Adjacent to its free edge, the flap member 33 carries a stop rod 37 which extends throughout the entire length of the roller 10. The stop rod 37 is fixed to a pressureapplying portion 38 of the flap member 33 and is normally slightly spaced from the surface of the roller 10. Outward movement of the flap member 33 is limited by engagement of its inner edge portion with the adjacent edge of the trough 22 which serves as a stop member. The flap member 33 may lightly contact the roller 10 during operation of the applicator due to gravitational forces or it may be slightly spaced therefrom.

The radius of curvature of the cylindrical trough 23 is somewhat greater than the radius of curvature of the roller 10 so that there is wiping contact between the trough 23 and roller 10 as indicated at 39. At either side of the contact zone 39, paint may be received and subsequently picked up by rotation of the roller 10. The roller is loaded with paint by rolling it along the bottom of a pan containing a shallow depth of paint in the usual manner.

When painting a surface such as the surface 40 of FIG.

1, there is a free portion of the roller 10 indicated at 41 which operates to apply the paint.

When painting at a corner such as the corner defined by the surfaces 43 and 44 in FIG. 4, the roller 10 rolls along the ceiling 43. As the wall 44 is approached, the applicator is so manipulated that the free edge of the flap member 33 first enters the corner defined by the wall 44 and ceiling 43 before proceeding further. With the free edge of the flap member 33 held in the corner, the resilient roller 10 is further advanced along the ceiling 43 whereupon the pressureapplying portion 38 deforms the roller 10 into a substantially flap-sided cylindrical configuration and the stop rod 37 engages and becomes embedded in the deformed roller 10 thereby preventing rotation of roller 10. It will be observed that the pressure-applying portion 38 of flap member 33 extends from its free edge portion toward the pivot shaft 35. Further pressure applied to the roller 10 squeezes it against the ceiling 43 to fit the corner with the extreme corner-engaging portion of roller 10 backed up by the stop rod 37 so that it completely engages the peripheral surface of the ceiling 43 adjacent to the corner. Paint is thus applied only to the ceiling portion of the corner as shown in FIG. 4, 'While the flap member 33 acts as a shield or guard preventing the application of paint to the wall portion of the corner.

The applicator operates in a similar manner for corners other than those defined by a wall and a ceiling.

The roller 10 described above takes up paint throughout its entire volume. In order to confine the paint to the outer portion of the roller, a sectionalized roller may be used as illustrated in FIGS. 5 and 6.

The sectionalized roller, which is designated generally as 50, comprises an inner cylindrical core portion 51 and an outer cylindrical portion 52 coaxially surrounding the inner portion 51. Interposed between the inner portion 51 and the outer portion 52, there is a barrier layer 53. The barrier layer 53 extends over and covers the ends of the inner portion 51 as indicated at 54 so that the barrier layer 53 and tubular core 11 completely enclose the inner core portion 51 and prevent the entry of paint into the inner portion.

Both the inner portion 51 and the outer portion 52 are formed of resilient spongy porous material having effectively the same resiliency. The barrier layer 53 is formed by coating the inner portion 51 with a liquid impervious material which, after hardening, is sufficiently flexible to provide a composite roller of effectively uniform resiliency so that it may be squeezed into a corner as shown in FIG. 4. The barrier layer 53 closes the pores of the inner portion 51 so that it is sealed 01f from the outer portion 52. As stated'above, the barrier layer 53 also extends over and closes the pores at the ends of inner portion 51 as indicated at 54 whereby paint is prevented from entering the ends of the inner portion 51.

The sectionalized roller 50 is easier to clean than the roller 10 because the depth of penetration of paint into the roller 50 is limited by the barrier layer 53. There is no central accumulation of paint which must be removed to revent its hardening and interfering with the smooth operation of the roller or the squeezing of the roller intoa corner.

Referring to FIGS. 8 through 12, the roller which is designated generally as 60, comprises an inner core portion 61 ensleeved within an outer cylindrical portion 62. The inner and outer portions 61 and 62, respectively, are formed of spongy polyurethane and are separated by an open-ended cylindrical barrier layer 64 of rubber or equivalent impermeable flexible material which extends throughout the entire length of the outer portion 62 along its inner surface.

The barrier layer 64 is formed by brushing or spraying the inner cylindrical surface of outer portion 62 with rubber or similar material which is initially in liquid form. While this coating is still wet, the shorter inner core portion 61, likewise coated, is inserted within the outer portion 62 and axially centered to produce equal projecting end portions 65 of the outer portion 62 which extend beyond the ends of the core portion 61. The liquid coating subsequently hardens to form the tough impermeable barrier layer 64 which is sufficiently flexible so that the composite roller 61 is effectively uniformly resilient throughout its entire volume.

In the arrangement illustrated in FIG. 10, the shaft consists of a hollow tubular portion 66 and a solid portion 66 which is freely slidable within the tubular portion 66. A collar 68 is fixed to the outer end of each of the shaft portions 66 and 66'. The stub shaft projections 32 are located outwardly beyond the collars 68 and engage the end plates 24 and 25 as described above. The collars 68 are pressed outwardly by the resiliency of the inner core portion 61 of the roller 60, the spring 16 of FIG. 3 being omitted. In order to increase the active compressional areas at the ends of core portion 61, end washers 69 of suitable resiliency are interposed between the collars 68 and the ends of the resilient core 61. The end washers 62 also act as guard members protecting the ends of the core portion 61 from contact with the paint being applied. The recessing of the ends of the core portion 61 prevents engagement between the outer ends of portion 61 and the end plates 24 and 25 the inner surfaces of which are normally coated with wet paint when the applicator is in use.

As illustrated in FIGS. 8 through 12, the applicator may be used with either of two flap members. The wider flap member 70 is shown in FIGS. 7 and 11. The wider flap member 71 differs from the flap member 33 described above in that the stop rod 37 is omitted. Referring to FIG. 11, it will be observed that omission of the stop rod 37 leaves the roller 60 free to resume rotation as the applicator is withdrawn from the squeezing position shown in solid lines to the ceiling painting position shown in dot-dash outline. It is desirable to obtain rotation of the roller 60 accompanied by rolling contact with the ceiling 43 while the edge of the flap member 70 is still engaged in the corner between the ceiling 43 and wall 44. The normal paint applying operation involves rolling contact. With the roller 70 locked against rotation, a wiping rather than rolling contact is obtained near the edge of the ceiling which may result in a non-uniform paint distribution at and adjacent to the corner.

A narrower fiap member 71 shown in FIG. 8 may be substituted for the wider flap member 70 illustrated in FIG. 7. The narrower flap member 71 is shown assembled in the applicator in FIG. 9. The free longitudinal edge of the narrower fiap member 71 is shown provided with a rounded bead 72 so that the edge will slide smoothly without scratching a surface with which it is pressed into contact. Each of the flap members 70 and 71 comprises a pressure-applying portion 73.

The narrower flap 71 operates in the manner illustrated in FIG. 12. The applicator is brought from the position shown in dot-dash outline until the bead 72 engages the underlying shingle 74 without touching the roller 60. The flap member 71 is then pressed flat against the underlying shingle 74, with the pressure-applying portion 73 squeezing the roller 60. With the flap member 71 held fiat against the underlying shingle, the applicator is moved upwardly with the flap member 71 sliding along the surface of the underlying shingle 74. Continued upward movement forces the roller 60 into the downwardly opening slot 75 between an intermediate shingle 76 and an overlying shingle 77. This final position is shown in FIG. 12. In this manner, the applicator of FIGS. 8, 9 and 12 operates rapidly and etficiently for the painting of shingle siding without the need for using a brush to apply paint within downwardly opening slot 75.

It will be observed that the corner painting wider flap member 70 is tangent to the roller 60 in its uncompressed condition about half way between its outer free edge and the pivot rod 35. The slot painting narrower flap member 71, however, terminates substantially along its line of tangency with the roller in the uncompressed condition with the beaded edge 72 located slightly beyond the line of tangency. -It will also be observed that the pressure-applying portions 73 of the flap members and 7-1 are flat and that an obtuse dihedral angle is formed between each presure-applying portion 73 and the fiat connecting portion 7 8 which extends between the pressureapplying portion 73 and the pivot shaft 35. This obtuse dihedral angle offsets the pressure-applying portion 73 so that the housing 22 is clear of the wall 44 or shingle 74 when the roller 60 is deformed as shown in (FIGS. 11 and 12, respectively.

Referring to FIGS. 13 through 17, the trough 22 of housing 21 is provided with enlarged end plates and 81 so arranged that the pivot shaft 35 extends along the edge 82 of the trough 22 exteriorly of the trough. The pivot shaft 35 is provided with end portions 83 and 84 of reduced diameter which are both slidably and rotatably journaled in the end plates 80 and 81, respectively.

The helical compression spring 36 yieldingly urges the flap member 85 leftwardly as viewed in PIG. 13 so that the reduced diameter end portion 83 of pivot shaft 3-5 is maintained continuously but releasably engaged in the end plate 80. The reduced diameter end portion 84 normally projects beyond the end plate 81. The end portion 84 is of suificient length to permit the flap member 85 to be moved rightwardly as viewed in FIG. 13 against the yielding action of spring 36 for a distance sufiicient to withdraw the opposite reduced end portion 83 from engagement with the end plate 80 for removal of the flap member 85 from the housing 21. The edge 82 of the trough member 21 is shown in FIGS. 13 through 16 provided with a U-shaped reinforcing member 87 which increases the rigidity of the edge '82. The fiap member 85 is attached to the shaft 35 by being bent around the shaft 35 so that the flap member 85 is firmly secured to the shaft 35. Approximately midway between the ends of the shaft 35, a cam member 88 is so mounted that it embraces the portion of the fiap member 85 which is wrapped around the shaft 35. The cam member 88 is thus constrained to follow movements of the flap member 85 between the inactive position illustrated in FIG. 15 and the operative position shown in FIG. 14.

With the flap member 85 in its inactive position illustrated in FIG. 15, the roller may be used without interference by the flap member 85 as if the flap member 85 had been removed. Cam member 88 retains the flap member 85 in the inactive position. With the flap member 85 in its active position shown in FIG. 14, the applicator may be used as described above in connection with FIG. 11 for the application of paint in corners. With a narrower flap member 85, the applicator may be used as described above in connection with FIG. 11 for painting shingles. The cam member 88 permits forced pivotal movement of flap member 85 while preventing free movement caused by its weight.

In FIG. 17, the edge 90 of the trough 22 is rounded and the U-shaped reinforcing member 87 is omitted. A cam member 91 is mounted on the shaft 35 for rotation with the flap member 85. The cam member 91 has arcuate recesses 92 and 93 formed in opposite edge portions thereof. One of the two recesses 92, 93 is engaged by the rounded edge 90 with the flap member 85 in its active position shown in FIG. 14 and the other recess is engaged by the edge 90 when flap member 85 is in the inactive position shown in FIG. 15.
